Google has come up with a new initiative to fight internet trolls. A troll is someone who posts harmful content on internet blogs, chat rooms, and other social media sites with the intention of provoking other users in a negative way. Using a new artificial intelligence tool called “Perspective”, which was released on Thursday, internet users are able to feed online content into the site which can be rated by other users for its potential to cause harm to others. The tool also scans the internet for harmful content, which can also be rated by users. The site generates a “toxicity score” based on user feedback, which users can use to decide whether they want to participate in certain conversations and posts. News and blog sites can use Perspective to monitor their comment section. Lastly, users can feed certain words and phrases into Perspective to generate a score on how harmful that content is according to other users who rated the content.
